Virtual LANs
VLAN names must begin with an alphabetical letter. The names can be no longer than 32 characters and
must begin with an alphabetic character. The remainder of the name can be alphanumeric or contain
underscore (_) characters. VLAN names cannot be keywords.
NOTE
If you use the same name across categories (for example, STPD and EAPS names), Extreme Networks
recommends that you specify the identifying keyword as well as the actual name. If you do not use the
keyword, the system may return an error message.
VLAN names can be specified using the tab key for command completion.
VLAN names are locally significant. That is, VLAN names used on one switch are only meaningful to
that switch. If another switch is connected to it, the VLAN names have no significance to the other
switch.
NOTE
You should use VLAN names consistently across your entire network.
Default VLAN
The switch ships with one default VLAN that has the following properties:
• The VLAN name is default.
• It contains all the ports on a new or initialized switch.
• The default VLAN is untagged on all ports. It has an internal VLANid of 1.
Renaming a VLAN
To rename an existing VLAN, use the following command:
configure vlan <vlan_name> name <name>
The following rules apply to renaming VLANs:
• After you change the name of the default VLAN, it cannot be changed back to default.
• You cannot create a new VLAN named default.
Configuring VLANs on the Switch
This section describes the commands associated with setting up VLANs on the switch. Configuring a
VLAN involves the following steps:
1 Create and name the VLAN.
2 Assign an IP address and mask (if applicable) to the VLAN, if needed.
